Method and system for biometrically enabling a proximity payment device
First Claim
1. A method for verifying payer identity to validate use of a payment card in a proximity payment transaction attempted through a point-of-sale device, the method comprising:
- providing an electronically coupled biometric-reader in combination with the payment card to a registered payer for proximity payment use in the field, wherein the combination is physically disposed in a common housing, and wherein the combination comprises a reference biometric parameter corresponding to the registered payer;
using the biometric reader in the field to measure the payer'"'"'s biometric parameter, comparing the measured biometric parameter to the reference biometric parameter corresponding to the registered payer, and then for positive comparison validating use of the payment card for the proximity payment transaction.

Abstract
A self-validating payment device for making proximity payment transactions through a point-of-sale device is provided. The payment device includes electronics for wireless communication of stored or processed payer information to the point-of-sale device. A biometric reader is integrated into the payment device. A biometric measurement of a user of the payment device in the field is compared internally with a reference biometric measurement corresponding to the user to whom the payment device is registered. The payment device self-validates itself for use according to the results of comparison.
